Mechanical Q-Factor in the Earth’s Upper Inner Core Inferred from PKiKP Coda Waves
Published in Izvestiya, Physics of the Solid Earth
Abstract—Based on the alpha-shape computer-graphics analysis of coda envelope of the waves from nuclear explosions reflected from the inner core boundary (PKiKP), the estimates of the mechanical Q-factor are obtained for nine reflection regions beneath the Arctic, Central, and Southeast Asia with the average Q = 447 ± 43. The coda formation mechani...
